The German spoof is all well and good but I think Hann has raised a fair topic here.

I think the location (ledge, hanging stance etc) would have to depend on the type of rock as well as the personal preferences of the two or three climbers involved. Personally, I would take it up a notch and try get some on lead, but that's just me.

I had a look at the Petzl 8003 full body harness, it definitely seems best suited to the job. With a traditional sit harness the waist belt and tie in points are a lot lower than on the full body harness from Petzl and often get in the way of those advanced positions.

On the harness's page on Petzl's website I noticed there was a link to a PDF on "Tips for Protecting Your Equipment", some knowledge that could come in handy when one is getting down in the vertical world, we all know that there's nothing worse than getting you nuts stuck in a crack. There are also some handy tips on prolonging the usable lifespan of your equipment
